Digital Advanced Vacuum Gauge 0.1 mTorr to 1000 Torr (HVG-2020B)
The HVG-2020B wide range, dual-sensor vacuum gauge takes measurement to the next level. With a Piezo based sensor and a thermal-based Pirani sensor accurately and confidently measure pressures across seven decades. The Piezo sensor is media isolated, gas composition independent, and periodically zeroed by the Pirani sensor. An ambient thermal sensor enables the instrument to adjust for temperature and therefore better accuracy.
